1991年6月3～6日在芬兰赫尔辛基工艺学院召开了以《遥感:为地球管理服务的全球监测》(这里指的是全球环境管理和自然资源合理利用问题)命名的第十一届地球科学和遥感国际例行会议。之所以选择这个名称命题,是出自于全球生态学问题日益增加的急迫性和分析遥感可能性的必要性,以便为全球环境变化监测和全球变化预测提供所需的信息。由于《地球科学和遥感国际会议(IGARSS91)主要在地球科学和电机及电子工程师学会(IEEE)以及国际无线电科学协会(URSI)支持下召开的,因此有关研究被动和主动遥感方法及应用的报告却成了大会的主要内容。
The 11th Geosciences, named after “Remote Sensing: Global Monitoring for the Management of the Earth” (here referring to the issue of global environmental management and the rational use of natural resources) was held at Helsinki Institute of Technology in Finland from June 3 to June 6, 1991. And remote sensing international regular meeting. The reason for choosing this title proposition stems from the growing urgency of global ecological problems and the need to analyze the possibilities of remote sensing in order to provide the required information for global environmental change monitoring and global change prediction. Since the International Conference on Geoscience and Remote Sensing (IGARSS 91) was held mainly with the support of the Institute of Geosciences and Institute of Electrical and Electronics Engineers (IEEE) and the International Association of Radio Science Societies (URSI), reports on methods and applications of passive and active sensing Became the main content of the conference.
